To allwhom it may concern: 7

Be it known that I, OsoAR 'HEYMAN, a

citizen of the United States, residing at New York, and whose post-ollice address is No; 71 Nassau street, city, county, and State of New York, have invented certain new and useful Improvements in J ointed"Jewelry and Processes of Making Same; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

, such pieces.

The invention relates tojointed pieces of jewelry and the like, particularly to a series of jointed pieces suitable for .makingfbracw lets, and to an improved method of making The-following disclosure of the preferred form or'practice of the invention deals with the formation of a section of a bracelet, since that is the purpose to which the invention is primarily directed, but it will be un derstood thatcthe invention is applicable to the jointing of any piece of jewelry or other article in which the parts are small and delicate and consequently difficult to handle.

It is common practice to make up brace lets by uniting aseries of sections to one another by means of hinges. For this purpose thepractice is to form in the abutting surfaces of two sections, half cylindrical recesses adapted to receive small sections of tubing which really constitute the knuckle members of ahinge. ing are secured to the abutting facs of the sections in such manner that the tube seetions will fit into one another in the form of a hinge and then a pintle is run through the tube sections to unite the parts. This involves av series of welding operations corresponding to the number of knuckle members in the hinge; it is a tedious and delicate operation which can beperformed only by which is weak because the tube sections are separate attached piec es which cannot be reliably secured in filace.

' The purpose of render this operation less difficult and at the same time to produce an article, of manufacture in which the hinges are much more s curely fastened to the hinged bar sections.

or the like. Tothis end I emplop instead, of the tube sections usually used for the weldingl that the hinge These sections of tuband it results in a hingethe present invention is to knuckle members, pairs of hinge plates such hinge plates in one piece and the canbe produced at very slight expense. n accordance with'my invention, these hinge plates, preferably integral with the knuckle members, are secured to the abutting surfaces of the sections to be hinged together. This-is most conveniently and satisfactorily accomplished by uniting the hinge plates to the adjacent surfaces of the sec 'ons by a process of welding, and in using he word I intend to.- in'clud \processes of soldering. Ordinarily, t e welding will be effected :by Solid ring wit the same 'metal Slates and bar sections are made of, tha is, by? auto'gdnous soldering; but it may be. effected by the mere application of heat or pressure orlby using a different metal as solder. The hinge plates so united with the bar sections are very secure and they are also easily with the application of' he nnich'smaller and more numerous knuc l e members; and bar sections to which these hinges'have been applied as compared I applied can be united "by bringing them to- I section the integral bar; Fig. 2 is a View looking at the under side of the bar of Fig.

1; Fig. 3 shows the bar after the hinges have been applied and the bar has been cut into sections; Fig. 4 shows two sections of the completed bar separated at hinge; Fig. 5 is an end view of Fig. 6- shows two separated sections in perspective. I

In carrying out the invention, I start with an integral bar'of any desired shape. In Fig. 1 I have represented a channel bar 1. In this bar, at uniformly spaced intervals corresponding to the desired length of the individual sections of the completed her, I

one of the sections; and a cut hinge-receiving recesses 2. In these recesses I-place pairs of hinge plates 3, 4,

carrying cooperating knuckle members 5, 6.

These knuckle members are preferably formed integral withthe hinge plates. I then unite the plates 3 and 4 with theadjacent surfaces of the recess, and this is preferably accomplished by a process of Welding as-abovedescribed, and as indicated by the cross-section lines in Figs. 1, 2, 3 and; 6. A pintlc 7 is then run through the knuckle members and the hinge is completed. Aft-er this operation has been performed in each of the series of recesses of the bar, the bar is divided' into sections by cutting through from the top as indicated at S in Fig.3, the

' result bein a completed chain of bar sections hinged together. It will be understood that the Walls of the recesses 2- Will be slightly flared so that when the hinge i in place it will be slightly opened as indica ed in the drawings, and consequently when the sections are separated at 8, the-completed described.

bar atthe' hinges to divide it into sections;

substantially as described. a

2. The method of producing from an in tegral bar a plurality of bar sections hinged together for jewelry and the like, which consists in forming a series. of spaced hinge-' 40 receiving recesses 1n and extending partially through the bar, placing in the recesses pairs of ingeplates carrying cooperating knuckle members, Welding the plates of each pair to the adjacent surfaces of the recess, and cutting through. the bar at the hinges to divide it into sections; substantially as described.

3. An article for the manufacture of jewelry or the like, comprising hinged bar sections arranged end to end, each member be-.

ingrecessed at opposite ends so thatjan overhangis provided atop each of said recesses, anda knuckle-carrying hingeplate secured in each of said recesses so that the outer surface of each hinge plate forms a flush continuation of the end face of the overhang thereabove. I a 4. An article for use in the manufacture of jewelry an-lthe like, comprising an integral bar contain ng a series of hinge-receiv ing recesses, 'pairs of hinge plates in said 7 recesses and united with the adjacent walls thereof, andcooperating knuckle members carried by said hinge plates, substantially as In testimony whereof l aifix'my signature.
